Project Number: 3607-21000-010-00
Project Type: Appropriated

Start Date: Oct 01, 2005
End Date: May 15, 2008

Objective:
1. Develop breeder-friendly markers for QTLs linked to soybean cyst nematode and Phytophthora sojae resistance. 2. Identify QTLs for Coleopteran insect resistance of soybean. 3. Identify soybean germplasms for resistance/partial resistance to bean pod mottle virus (BPMV). 4. Develop novel soybean germplasm with disease and/or insect tolerance.

Approach:
Genes involved in disease and insect resistance and other target traits will be identified through molecular mapping. Segregating mapping populations will be developed for all target traits. The genes will be tagged with DNA markers to permit incorporation into advanced soybean germplasm. Molecular markers will be identified to facilitate marker-assisted selection of enhanced germplasm. Appropriate methods and technology will be identified or developed to facilitate gene identification and mapping. Soybean germplasms with resistance or tolerance to soybean aphid, beetles, and Phytophthora root rot will be developed through a combination of the conventional and marker assisted plant breeding approaches. Virus identification and detection procedures will be developed, and sources of partial resistance to bean pod mottle virus will be identified by greenhouse and laboratory screenings of plant introductions.
